The Star Wars extended universe is coming to the big screen in a big way. Forest Whitaker's mysterious character in Rogue One: A Star Wars Story has been revealed, and it's a familiar character to all Clone Wars fans.

Whitaker's character has only been seen briefly in the trailer, as the warrior who asks Jyn, "If you continue to fight, what will you become?" As it turns out, that character is Saw Gerrera, who was first seen in season five of Clone Wars and has shown up periodically in Extended Universe works.

In Clone Wars, a younger Saw and his sister Steela fought beside Anakin Skywalker when he was a Jedi, and were trained by him, Obi-Wan, and Ahsoka Tano. They were part of an insurgent group fighting a droid army of Separatists, and the events of the season led to deep trauma and mistrust of authority. In Rogue One, which takes place more than two decades later, he is more grizzled, more shell-shocked, and more controversial. He represents the radical sect of the Rebellion who do morally questionable things to get results, as is seen in Claudia Gray's Bloodline, in which a character refers to his group's "terrorist tactics."

"Consider him kind of a battered veteran who leads a band of Rebel extremists," Lucasfilm president Kathleen Kennedy told EW. "He's on the fringe of the Rebel Alliance. Even [they] are a little concerned about him."

So. Saw Gerrera. Yes, to reiterate, he was an idea developed for the proposed live action TV show, but was introduced in The Clone Wars.
